About the configuration method of environment variables in thinkPHP5.0 framework
This article mainly introduces the thinkPHP5.0 framework environment variable configuration method, and analyzes the function, definition, configuration and related precautions of environment variables in thinkPHP5.0 in the form of examples. Friends in need can refer to it
The example in this article describes the thinkPHP5.0 framework environment variable configuration method. Share it with everyone for your reference, the details are as follows:
Allows the use of environment variable configuration, and the priority level is higher than in the configuration file, because when reading the configuration parameters, it will first determine whether the environment variable exists This configuration.
During the development process, you can simulate environment variable configuration in .env under the application root directory. The configuration parameter definition format in the .env file adopts the ini method , for example:
app_debug = true app_trace = true
If your deployment environment has separately configured environment variables, please delete the .env configuration file to avoid conflicts.
Environment variable configuration parameters will all be converted to uppercase, the value is null, no and false are equivalent to "", and the value of yes and true are equivalent to "1".
The default environment variable prefix of ThinkPHP5.0 is PHP_, which can also be reset by changing the ENV_PREFIX constant .
Note,Environment variables do not support array parameters. If you need to use array parameters, you can use underscores to separate the configuration parameter names:
database_username = root database_password = 123456
Or use
[database] username = root password = 123456
Then you can use the following two methods to obtain:
Config::get('database.username'); Config::get('database.password'); // 同时下面的方式也可以获取 Config::get('database_username'); Config::get('database_password');
The above is the entire content of this article. I hope it will be helpful to everyone’s study. For more related content, please pay attention to the PHP Chinese website!

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
